The Citi® / AAdvantage® Executive World Elite Mastercard® and the United Club℠ Infinite Card are both premium airline credit cards offering substantial travel perks and rewards. The United Club Infinite is the better choice if you’re indifferent between United and American Airlines but want a high sign-up bonus, a low annual fee or more miles for dining and travel purchases.
However, the AAdvantage Executive World Elite remains a strong contender for American Airlines loyalists due to its Admirals Club membership, 4X miles on AA purchases and broad accessibility.
